Description

A kind of Synergistic insecticidal compositions and its application containing etoxazole and silicon ethofenprox
Technical field
The invention belongs to pesticide field, and in particular to a kind of desinsection using etoxazole with silicon ethofenprox as principle active component Composition and its application.
Background technology
Etoxazole (etoxazole), structural formula are:
Etoxazole is a kind of acaricide of brand-new tool special construction of SUMITOMO CHEMICAL Chemical Co., Ltd. research and development, belongs to 2,4- Diphenyl-oxazole derivatives quasi-compound, is a kind of selective acaricide.Its mode of action be suppress mite ovum embry ogenesis with And from young mite to the molting process into mite, it is effective to ovum and young mite, to invalid into mite.Therefore its optimal prevention time is evil mite Harm initial stage.This medicament rain fastness is strong, and lasting period length, dosage is low, environmentally safe, to beneficial insect and beneficial mite non-hazardous Or harm is minimum.
Silicon ethofenprox (Silafluofen), structural formula:
Silicon ethofenprox is siliceous pyrethroid insecticides, and effect is close to ethofenprox, available for rice, cotton-plant pest-insects Prevention.Effect is rapid, and insecticidal spectrum is wide, and ichthyotoxin is very low, is expected to use in paddy field.It is right suitable for prevention rice, vegetables, on cotton Homoptera Delphacidae special efficacy, while to various pests such as Lepidoptera, Semiptera, Orthoptera, coleoptera, Diptera and Isopteras There is good effect.It is especially notable to the prevention effect of rice hoppers.
Insecticide variety containing single component often existing defects in pesticide control of insect:Continuous use easily produces anti- Pharmacological property, insecticidal spectrum are narrow, it is impossible to provide comprehensive protection, peasant's drug cost height etc. for crop.It is various by two kinds or the coming year The combination of active ingredient can overcome disadvantages mentioned above to a certain extent to a certain extent.Two kinds or two with synergistic effect The combination mixture of kind above active ingredient, can improve preventive effect, and dosage, cost-effective with reducing active ingredient, slows down pest Resistance, which occurs simultaneously can expand to prevent, composes, and plays that more worms are simultaneous to be controlled, reduces the use cost of peasant.
The content of the invention
It is an object of the invention to for above-mentioned various problems, in order to overcome and delay the resistance to the action of a drug to existing pesticide, expand Big insecticidal spectrum, enhancing drug effect, reduce drug cost, so as to provide a kind of prevention various crop Homoptera, Lepidoptera, mite class disease pest Harmful Pesticidal combination.
It is a still further object of the present invention to provide the purposes of the Pesticidal combination.
The measure of the present invention is realized by following measures.
A kind of Synergistic insecticidal compositions containing etoxazole Yu silicon ethofenprox, the Synergistic insecticidal compositions are with etoxazole and silicon ether Chrysanthemum ester is principle active component, wherein, the weight ratio of etoxazole and silicon ethofenprox is 1:60~60:1.
The more excellent weight ratio of the Pesticidal combination, wherein etoxazole and silicon ethofenprox is 1:50~30:1.Further It is preferred that the weight ratio of etoxazole and silicon ethofenprox is 1:20~20:1, the still further preferably weight ratio of etoxazole and silicon ethofenprox For 1:1~10, the weight ratio of most preferably etoxazole and silicon ethofenprox is 1:5~10.The weight ratio of etoxazole and silicon ethofenprox is also Can be 1:10、1:5、1:10、1:2、1:3、1:1.
The weight ratio of preparation shared by the two kinds of active principle accumulations of the Pesticidal combination, wherein etoxazole and silicon ethofenprox For 0.5%~90%, preferably 1~60%.
The Pesticidal combination, using etoxazole and silicon ethofenprox as principle active component (active ingredient) and auxiliary agent and/ Or excipient is processed into any one formulation allowed on pesticide.The formulation that can be processed into is missible oil, suspending agent, aqueous emulsion, micro- Emulsion, pulvis, wettable powder, dispersible oil-suspending agent and water dispersible granules etc..The auxiliary agent can use detergent alkylate Sulfoacid calcium, alkylphenol polyoxyethylene ether, polyoxyethylene polyoxy propylene block compound (such as agriculture breast 33#), Nonyl pheno Ether etc., excipient include cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water.Above auxiliary agent, Excipient and other agriculturally known auxiliary materials can be alone or be used in combination.
The above-mentioned Synergistic insecticidal compositions containing etoxazole and silicon ethofenprox are preparing prevention cereal crop, fruit tree, flower Grass, cotton, tea tree, the Homoptera on vegetables, Lepidoptera, mite pest insecticide in apply.The lepidoptera pest is excellent Elect bollworm, leaf miner, beet armyworm as, homoptera pest is preferably plant hopper, and mite pest is preferably red spider, tetranychid, complete Pawl mite.
The present invention Synergistic insecticidal compositions antagonism mite pest have significant preventive effect, particularly with tetranychid, red spider, The various pests that Panonychus citri etc. easily produces resistance have good preventive effect;And suppress pest to unitary agent (etoxazole Or silicon ethofenprox) the resistance to the action of a drug produce and at the same time can prevent the pests such as Homoptera, Lepidoptera.
The Pesticidal combination of the present invention compared with prior art, produces following beneficial effect:(1) compared with single dose, the group Prevention of the compound to pest has notable synergistic, and prevention effect significantly improves;(2) one medicines more control, a dispenser can at the same time anti-Zhiduo County Kind pest, reduces prevention recruitment cost;The desinsection prepared by the Synergistic insecticidal compositions containing etoxazole and silicon ethofenprox Medicine is preventing mite class at the same time, and can prevent Lepidoptera, homoptera pest, especially to cotton boll worm, small brown rice planthopper and beet night Moth has good preventive effect, reaches the effect that a medicine is controlled more.(3) alternative high-toxic pesticide, and field dosage is greatly reduced, have Effect reduces environmental pollution and pesticide residue;(4) have concurrently quick-acting and long-acting;(5) compared with etoxazole single dose, production and application cost Reduce;(6) suppressing pest strengthens the resistance of pesticide.
